Mouth ulcers
Mouth ulcers (aphthous ulcers) are sensitive, uncomfortable sores in the mouth, often white or yellowish with a red, inflamed border. You may find them on the inside of your cheek, your lips or under your tongue. The cause is still unknown, but they usually clear up on their own after about 7 days.
How mouth ulcers develop
The cause is still unknown. Possible causes include a tooth rubbing against the tongue or cheek. A vitamin deficiency, certain foods, anaemia, hormonal changes, lack of sleep and even stress also seem to play a role.
What can you do about mouth ulcers?
If the discomfort is unbearable, you can get a dab-on liquid from the chemist or pharmacy to relieve the pain. Good oral hygiene, possibly together with an antibacterial mouthwash, is also important. If you have a mouth ulcer, avoid acidic foods such as citrus fruits and tomatoes, as the acid irritates the ulcer. If mouth ulcers persist for longer than 2 weeks, it is advisable to contact us.
Preventing mouth ulcers
There are indications that daily use of a toothpaste with a mild foaming agent (such as Elmex, Zendium or Parodontax) helps prevent mouth ulcers.
